1. Performance of cover crops under two irrigation regimes in the Coastal Tablelands region of Brazil

ABSTRACT There is currently a lack of information regarding the performance of cover crops grown in the Coastal Tablelands region in the North of the Brazilian state of Espírito Santo, where zero tillage is increasingly being adopted. The objective of this study was to evaluate the agronomic performance of six cover crops (ruzi grass, jack bean, and the mil

2. Broccoli in succession to pearl millet: nutrient cycling, production and soil chemical attributes

ABSTRACT For its production, broccoli requires large quantities of nutrients in relatively short periods. As a conservation technique, the no-tillage planting of broccoli over the pearl millet straw in succession may interfere with the dynamics of nutrient release, inflorescence production and the chemical attributes of the soil. The objectives of this work

3. Conservation system improves soil microbial quality and increases soybean yield in the Northeastern Cerrado

ABSTRACT The conservation tillage systems is based on the surface protection by crop residue and reduced soil disturbance. These two principles can favor the soil quality and promote sustainable agricultural systems. The study was developed with the objective of measure soil microbial biomass, soil basal respiration, enzymatic activity and soybean yield in c

4. Nondestructive analysis of photosynthetic pigments in forage radish and vetch

ABSTRACT Chlorophylls and carotenoids are the main photosynthetic pigments in plants, and photosynthetic potential can be used to determine the nitrogen fixation or cycling capacity of cover crops. Therefore, this study quantified and compared the content of photosynthetic pigments in Raphanus sativus and Vicia sativa by using two different methods, namely t

5. Foliar application of molybdenum on cover crops and response of common beans in successive cultivation

ABSTRACT The effects of foliar application of Mo and use of N from cover crops (Crotalaria juncea L. and Canavalia ensiformis (L.) DC) on the performance of common beans were investigated in this study. Field experiments were carried out in a succession planting system (cover crops - common beans), and nitrate reductase activities were evaluated in the labor

6. Is Increasing Doses of Imazapyr + Imazapic Detrimental to the Main Crop Rotation Alternatives to Flooded Rice?

RESUMO: A mistura formulada de imazapyr + imazapic é o principal herbicida usado para o controle de plantas daninhas em arroz no sistema Clearfield®. O uso contínuo de altas doses pode aumentar sua atividade residual no solo. O objetivo deste trabalho foi determinar a sensibilidade de culturas de cobertura e soja em rotação com arroz irrigado a diferent

7. Maize productivity in succession to cover crops, nitrogen fertilization and inoculation with Azospirillum brasilense

RESUMO O uso de microrganismos na agricultura como Azospirillum brasilense e o cultivo de plantas de cobertura na entressafra, juntamente com a adubação nitrogenada, podem ser alternativas interessantes para aumentar a produtividade das culturas. Este estudo teve por objetivo avaliar os componentes de crescimento e de produção e o teor de nitrogênio do

8. Annual cropland mapping using data mining and OLI Landsat-8

RESUMO No Estado do Paraná, Brasil, não há grandes mudanças nas áreas cultivadas com culturas anuais, principalmente devido a leis ambientais que não permitem expansões para novas áreas. Há grande contribuição das culturas anuais para a demanda doméstica de alimentos e econômica nas exportações. Assim, a área e distribuição das culturas anu

9. Summer Cover Crops Shoot Decomposition and Nitrogen Release in a No-Tilled Sandy Soil

ABSTRACT Cover crops have numerous benefits when used in a no-till system. Understanding the processes of decomposition and N release of summer cover crops (SCC) may help select species and management to be used in cropping systems. This study aimed to evaluate C and N loss of SCC shoots. Six SCCs were evaluated: velvet bean (Mucuna aterrima), pearl millet (

10. Effects of cover crops on soil hydraulic properties and yield in a persimmon orchard

ABSTRACT This study evaluated the effects of cover crops on yield and soil hydraulic properties of a persimmon orchard in Turkey. Soil samples were taken from 0-20 and 20-40 cm. Profiles of a clay soil and field capacity, permanent wilting point, available water capacity and saturated hydraulic conductivity of the samples were determined. Festuca rubra subsp

11. Cover cropping system and mulching can shape soil microbial status in fruit orchards

ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

12. Soil physical properties and soil organic carbon content in northeast Brazil: long-term tillage systems effects

ABSTRACT Concerns about the negative effects of agriculture on soil physical quality and soil organic carbon (SOC) pools have spurred on the adoption of conservation tillage systems in tropical regions. This study aimed to evaluate the long-term impacts (16th year) of conventional (CT), minimum (MT) and no-tillage (NT) practices and different cover crops (su
